    Hello,

    I am working in opl cplex and i have to know the signification of the different columns in Engine log (journal du moteur) section.

    Node : I think in this colum the number of treated node is represented.

    Nodes Left : it is clear for this column.

    Objective : I want to know the signification of this column. What represents. If it represents a linear relaxation, could we have a value (in green, see attached file) lower than the first linear relaxation (in red).

    Thank you for your help.

     

    Best regards.

    Hi,

    I recommend in the documentation

    IDE and OPL > CPLEX Studio IDE > IDE Tutorials > Understanding solving statistics and progress (MP models)

    Examining the engine log

    regards
